The valves are designed to block the flow of the medium (water or steam) in the pipeline. The valves are installed on horizontal or vertical sections of pipelines. The position of the spindle for valves with a flywheel is any; For valves equipped with a gearbox with a cylindrical hook, installation is allowed on horizontal areas with a spindle up within the upper semicircle. The valves equipped with a conical hook gearbox are installed on horizontal sections of pipelines in the spindle position within the semicircle and on vertical sections of pipelines with a spindle horizontally.
Crossing the flow of the medium is achieved by planting plates on the saddle of the valve. The plates fixed on the fork make a progressive movement from top to bottom, due to the transformation of the rotational movement of the spindle nut into the progressive spindle. The rotational movement of the spindle nut is reported by the flywheel, or the gearbox (KZ, CZ). The gearbox is connected to the executive mechanism of the hinge clutch. The tightness of the valve cavity is achieved due to the welding of the valve body to the pipeline and the installation on the cover of the cover of the cover.
The supply of the medium to the cavity is carried out from either side.
